you basically hit it on the money. i do not know about these rc helicopters, but on a real helicopter the blades change the angle of attack or pitch. an example:
when a helicopter is on the ground and is preparing to take off, the rotors are actually spinning at the same speed as if it was flying. to lift off the ground the pilot pulls back on the collective, (which controls the pitch of the blades). so when you watch a movie and a helicopter makes a louder noise, as if the blades were speeding up, when it is taking off. the noise you here is fake. the rotors are actually spinning at the same speed.
as for the rc copter being able to do all those maneuvers, the only reason i can give is that it is alot smaller therefore it can handle more g forces.
cool vid though.
